Ten innovations in Design specifications of Android4.0 Design

After reading and translating the Android design guidance, compare the Android 4.0, 4.1, 4.4, and Android and earlier app design guidance, I have summarized the 10 major changes to the design specifications after Android 4.0. I would also like to thank Boyou for your support for my articles. The reading volume of articles in the important design concepts series has been soaring recently, I was encouraged to continue writing this series of articles.

I. navigation bar

From the previous physical key navigation (Return, menu, search, home page) to the virtual key embedded in the screen (Return, home page, recent task ).

Remove the menu items and search items from the navigation bar, and display the previously opened applications that appeared by pressing the homepage key directly in the navigation bar.

Ii. Operation bar

The operation bar is the most important structural element in android applications. It provides a consistent navigation platform surface for users' application behavior. To put it simply, you can use the operation bar to complete the same functions as those provided by the previous interface when operating any interface opened in your application.

For most applications, the Operation bar is divided into four different functional areas.

(1) Application icons

In other words, we can demonstrate the identities of different applications.

(2) View Control

If our applications can display data in different views, you can switch the views/

(3) Action Buttons

The most important function buttons of our application can be displayed here.

(4) more operations

Click to bring up some uncommon operations or about some system settings

You can also split the operation column into one main operation column, two top columns, and three bottom columns. If needed, the top bar can carry the tab tabs, and the bottom bar can carry the main operations and more collapsed operations (action overflow ).

When there is enough space for the horizontal screen display interface, the split operation bar can be flexibly merged. As shown in the Operation bar on the mobile phone side.

3. Multi-panel layout

Multi-panel layout is mainly for tablet development, that is, Fragement. I have introduced a lot of operations on Fragement layout in my previous blog post. Composite display on the same interface, effectively using the screen space of the tablet, flattening the hierarchical structure, and simplifying navigation.

4. Select

In the past versions, the long-pressed gesture was used to display context action operations and to select data after android4.0. In Android4.0, after a long press, a temporary context action bar will be overwritten in the action bar, and the context menu will not pop up. In the temporary situation action column, the content items on the current interface can be processed by a single user or batch.

In the new version

(1) You can select additional data by touch.

(2) When a temporary context operation column is promoted, the selected data is highlighted, and the temporary operation column is automatically determined to disappear.

(3) You can click the back button in the Operation bar to cancel the selection operation.

The four major innovations of android4.0 are shown above. I will continue to write about the version updates of android4.1 and 4.4 Later. Thank you for your support.
